  • Need input for my '02 T bird

    Hello friends, i have been seriously thinking of removing the whole hydrolic cooling pump system, and replacing it with electric fan and fan speed controller. I recently rebuilt the pump, now the actuator is bad, and i have air in the system, that seems not wanting to purge, so a constant squeel when warmer temperature. The car with current trim is 1 of only 94. ,, ideally would be to keep it stock, but this hydrolic system really sucks. What should i do ?

    There is thread here on TBN, The conversion is very complicated,due in fact that the charging system is underated for the addition of the electric fan. I also remember that you would have to manually control the fan when using the AC. My final thought was that was that it would cost more to convert than rebuild the whole system.

      All I can say is that my cooling system pump was replaced in the third year of ownership in 2004 and I now have 125,000 miles without a problem. If a problem came up I would replace it with the same system.

        I'm wondering if this change wouldn't require some computer reprogramming?

            In addition to the very good information given above, if you go to Forums, Thunderbird Garage, How to fix it, and type the following into the search box: "hydraulic to electric", there are a few older items relating to this. I don't recall hearing about anyone, other than the link Richard gave, doing this.

              Thank you all for the replies, as far as the parts for the conversion, i already did my homework. Using a flex a lite fan , pulls about 17 amps, which should be fine for the stock 110 amp alternator. The fan is rated for a 4,6 and 5,8 liter V8, roughly about 2800 cfm. The speed controller Is also by flex a lite, it iS a " PID" system, which means it starts the fan at 60% speed, 4seconds after motor starts, the sensor which is in the radiator , sends a signal to the unit, and fan slowly speeds up when getting warmer. There is also a wire to connect to the a/c compressor clutch, forcing the fan into hi speed when energized. This controller is also adjustable from 185 to 230 degrees in the radiator. Being a "PID" controller, there will be no amperage spikes to the alternator,,, which should help.

              i will keep all original parts to switch back if i ever sell the car, if originality is an issue...

                This is cool. My bird went in today for an overheat. I think it's just a hose, but the "hydrolic fan thing" makes me nervous. I bought some cosmetic parts from a wrecker who has a 2003 on hand. I may call back and see if I can buy that fan driver too, just in case. I wish Ford/Jaguar didn't reinvent the wheel on so many silly things....

                  Andy, your 2003 doesn't have the hydraulic fan system. That was 2002 only.

                    Best of luck with your project, it sounds like you have everything well thought out! Please share what and how you changed it so that it can be added to the data base.

                      You will also need a shorter fan belt for the conversion once you remove the pump. The car my kids are trying to put back together has a really bad leak at the pump, the high pressure line is bent so they are going to try replacing that first. FYI, I have a brand new NOS hydraulic pump and actuator for sale in the classified section, I also have a used pump and actuator.

                      Is the squeal coming from the pump or the fan?

                        Brad, as for the belt, i forgot to mention, but already purchased a 100" belt. The noise i hear comes from the hydrolics, sound like a bad power steering pump,and only whines when engine run hotter ( 87 deg. Day or hotter) or i turn on the a/c on, and the condensor blows hot air. But cold,, no noise. A hydrolIc specialist told me its trapped air in the system.
                        I am a Commercial / industrial Refrigeration mechanic, so tinkering and coming up with fixes is up my alley. I am almost positive that doing the swap to electric will give better cooling ( i monitor with a Livewire TS unit, on OBD connection) . I like to maintain between 190 and 198 , on the hottest days.

                        as for my actuator valve on the pump, i know its bad from testing. Fan speed should be controlled from amount of fluid this valve is putting out.( using a pulse signal from car's computer) When a/c compressor is engaged, it should open up and flow 100% to the motor. Mine doesn't do that. A actuator at the dealer here in Canada is $400 + 15% taxes.....

                          Merlot, I will definitvely keep all of you posted of the outcome, and how it works. Nice winter project while she sleeps in my garage over the winter.
